Yesterday Apple released tvOS 14.0.2 for Apple TV. The new version of the system has been marked as build 18J411.
List of Apple TV set-top boxes on which you can install tvOS 14:.
- Apple TV 4th generation / Apple TV HD
- Apple TV 4K
To install the latest tvOS system, go to Settings, System, Upgrades and then select Update Software. After a while, you should see information about the new version and then just download and install it.
The latest version includes enhancements, bug fixes and stability. Unfortunately Apple does not describe as changes were included in the system for Apple TV.
However, it is worth reminding that in tvOS 14, the novelties include support for 4K on YouTube, Picture-in-picture mode, multi-user support in Apple Arcade, Dom application, audio sharing, support for additional controllers, control center and wider support for HomeKit. Support for Apple Fitness+ and Apple One will be added this year.
